Porsche has announced that dealers the world over have begun taking orders for the company’s 918 Spyder. The plug-in hybrid will boast a 500-horsepower, 4.0-liter V8 engine and two electric motors capable of a combined 218 horsepower. Porsche says the hybrid powertrain will consume a mere 3.0 liters of fuel per 100 kilometers – or around 78 mpg. The German automaker hasn’t released any fuel economy estimates based on U.S. testing standards, though EPA figures are said to be on the way. Look for the gas-electric Porsche supercar to touch down on U.S. soil by late 2013.

If you want one, you better drop what you’re doing and get in line right now. The automaker says that it’s only planning to build 918 examples of the vehicle and that each of them will carry a lofty price tag of $845,000 plus destination and handling.

That’s a lot of coin, but with an electric motor at each axle, the 918 Spyder is projected to be able to launch to 60 mph in just 3.1 seconds. Top speed is said to be 199 mph, and Porsche believes that under the right conditions, the 918 will be able to drive on pure-electric power at speeds of up to 94 mph.
